The invention discloses a constant false-alarm energy detection method based on Markov transfer characteristics. The method comprises the steps of: according to the Markov transfer characteristics ofa main user, deducing the state of a current time slot main user by utilizing the state of a previous time slot main user, so that the judgement threshold is adjusted; and, comparing the observed energy with the judgement threshold, and judging whether a main user signal exists or not. According to the constant false-alarm energy detection method based on the Markov transfer characteristics disclosed by the invention, the detection precision can be increased; and the detection effect is superior to the detection effect of the traditional constant false-alarm energy detection method. 本发明公开种基于马尔科夫转移特性的恒虚警能量检测方法，方法根据主用户的马尔可夫转移特性，利用前时隙主用户所处状态来推断出当前时隙主用户的状态，进而调整判决门限；将观测到的能量与上述判决门限进行比较，判断出主用户信号是否存在。本发明种基于马尔科夫转移特性的恒虚警能量检测方法能提高检测精度，检测效果优于传统的恒虚警能量检测方法。
